Error-wise I didn't notice a ton of things, but:

> Bitcoin is designed to be a faster, cheaper and a more secure currency

> Security is achieved by having every participant do the verification themselves using [an] open protocol based on well[-]known cryptography methods

> The original software source code is open and available [to] everyone for review and improvement.

> The reward is halved approximately every 4 years until [a] total of 21 million bitcoins are generated around year 2140. Currently more than 9 million of bitcoins are available already.

Also "bitcoin" is not consistently capitalized.

That stuff aside, it's also not very idiomatic. I'm not sure what the ideal audience is, but if it's, say, my 60-year-old mom who doesn't really understand browser tabs, I don't think it's going to reach them. It's good for me though, as a programmer who doesn't specialize in crypto or know much about currency theory (if that's a thing).
Cofounder here, thanks for your feedback! This is indeed an early version, and to answer your points more precisely:

- This is indeed planned, and as you can see in the comments you're not the only one thinking that! It cannot be done with a bookmarklet but we will release Chrome and Firefox extensions that will have this feature.

- I don't get what you mean by "something sidebar-like", are you talking of a pannel on the top of your screen automatically displaying the summary if it exists?

- Yep, building an active community around tldr.io will likely be key to its success. We are thinking hard on how to do it, and if you have any ideas or suggestion they are more than welcome
I actually preferred the bookmarklet first approach (vs extension). I'd much rather test a bookmarklet first and then graduate to a browser extension.
Lockitron user here. Love it!
I've been using a MiCasa Verde[1], alongside the compatible KwikSet Deadbolts[2], an android app called Automator to accomplish the same thing. It's actually a little pricier but you get:

a. Remote entry -- unlock your door from afar.
b. A nice home automation system (mine's expanded to control lights and thermostat now)
c. Keypad and key-entry as backups

I love it. Being able to remotely lock and unlock your doors is super handy, whether it be for guests, contractors or what not. But what's really handy? Never worrying about locking yourself out of your house again.

If I could just get rid of my car key, I'd be thrilled.

We have one of these for our office too, and it works great :-). My only problem is that I want one for my apartment too, so I can stop carrying keys altogether.
I've heard (but can't find a link ATM) that it's not uncommon for people in developing countries have multiple phones or multiple SIM cards and will call on one or the other depending on that provider's current rates.
Nice site, really nice UI with the arrow pointing to the bookmark bar. A change in the color of the tl;dr; bookmark when there's a bookmark available would really go a long way! Great job!
I agree entirely. A lot of people on here seem to be clutching at straws at best. They offer a lot of "evidence" into why women aren't programmers without actually knowing anything.

In my head, positive discrimination is another form of discrimination. I know plenty of female programmers and they all got into programming because that's what they wanted to do, not because it was marketed as a career to them and not because they've never interacted with shitty co-workers.

If there's any problem with Software Engineering as a career it's the idea that it's a field for socially-inept nerds that sit in the basement and code away from the outside world. The "evidence" for this attitude is all over the place and in my mind this is as likely to turn women away from the field as much as it is men. When the field decides to stop allowing itself to be further commoditised and demand some respect (and better pay) we might see more women want to join us.
I think because he uses Windows, and wants to keep using it for years to come. I've always liked using Windows; I buy an OEM copy every time I build a new PC.

If we didn't use Windows, we wouldn't care about Win8. But, we'll switch to Linux if Windows doesn't support our hobby anymore.

Has someone suggested whiteboard proficiency is sufficient by itself?

Fair point, that is a straw man. I haven't experienced an all-whiteboard interview - there's always been more to it.

The whiteboard is meant to filter out people who suck.

I think that's what some interviewers have missed. They jump straight in at the deep end with difficult algorithmic puzzles, and don't ever do an easy one. I have experienced this.

Hmmm. The reviews where positive? All designers I know posted on Facebook and elsewhere (I'll try to find the launch thread here on HN which was not very positive either) things like 'He! MS bought a Themeforest theme!' and such. I quite like it I must say, especially the responsiveness (I had to go to some MS service on my Android S2 and actually it looked nice and worked well). But overwhelming positive? Not in the press I read (which has a lot of designers & coders & tech minded people).
Thanks for the feedback! What you describe would be a big improvement but is not feasible with a bookmarklet. We are planning on releasing a browser extension that will enable just this.
I've been on both sides of the fence: being interviewed and interviewing. The times I've been interviewed I felt (most of the times) that either the person questioning me had no complete understand of what he/she was asking --it could be possible he/she was a junior engineer-- or it was a tricky algorithm question. The thing is that not everyone thinks or plans the same way. Analytical thinking is different for everybody. Most of the time I like to solve problems first either by brute force or the simplest solution and then try to improve it, but the author of the post also got a very good point: "why".

When asked questions without a context, you have no motivation and they seem weird. If you want to know if I know what a b-tree or a hash-table is, or what is database normalization, just ask me to explain you what it is. I also, wouldn't expect a candidate to implement one of those things right out of their head... that's just crazy. I would expect for him to be able to use them or at least how they work.
If you need to see what I've done or how I perform against a particular issue your company might be having, code review of already code-reviewed code is a great, great way to test a candidate.

Github profiles are also a good indicator: it shows what you want, want motivates you, it can show real-world code that you have written.

Just talking of your experiences and how you've solved problems is also a good thing.
Nice to see Aparapi mentioned, the API looked promising but seemed to never really catch on. The concept of not having to ship code as Strings via native OpenCL wrappers like LWJGL was a nice usability improvement.

Hopefully Sumatra gains more momentum.
We use Lockitron on our offices and it has saved us a lot of trouble. Empirically people are a lot less likely to forget their phone than to forget keys, presumably because you use your phone for so many other things whereas most keys do nothing but get you into a single building.
"The company embedded an extremely lightweight HTTP server in the application itself. The HTTP server exposes native functionality through a very simple REST API that can be consumed in the embedded HTML controls through standard JavaScript HTTP requests"

As someone who has built a bridge between the WebView and iOS, why would you not use the native app url scheme (ex. linkedin:///goTo?storyId=1) and listen for them within the app? Even a lightweight HTTP server seems like serious overkill for this.
Reid Hoffman: The Career Escalator is Jammed -- and What To Do About It
Very true.

In one such interview, I was asked for a way to implement Rock Paper Scissors in OOP without using a conditional. I came up with a neat way to do it with modulo operations and array lookups, but that wasn't The Right Way. So I came up with a way to do it with exceptions, but it wasn't The Right Way. Finally I came up with the solution the interviewer had in mind, which used Java's method overloading (my background is not Java).

I'm not sure if I "passed" the interview, but it certainly didn't make me want to.

Hi, thanks for the feedback we're glad you like it!
To answer your questions:
- all tldrs are editable by users, so that the content can be refined by the community.
- we feel that tl;drs should convey the message and tone of the author of the underlying resource and as such shouldn't be opinionated.
- we would love to help content owners author, spread and control tl;drs of their content. If a content owner here is interested in talking with us about such opportunities, please contact us on twitter or by email

Probably a good idea to add a bit about serial, and sequences. This tends to confuse mysql people like myself.

I for instance don't know what happens when I copy or dump and restore a postgres table that relies on a sequence. Mysql auto-magically takes care of it by saving the next auto increment id in table dump or copy.

So it's true that everyone who disagrees with you is sexist? I dont think you mean that. Do you mean sexism should be addressed? There I agree, but that doesn't mean that every other point of view is sexist. And thats exactly on of the problems these kinds of discussion face. Every opposing argument is dismissed as "sexist" and not even taken slightly in account. And thats why some feminists are seen as fanatic- they refuse to take other points of view seriously, on the ground that it is sexist anyway. I think discussions don't work when you are aren't ready to accept other points of view, or at least take them serious.

Calling someone "mysoginistic" when he calmly and reasonably rational commented on a gender related issue, even if you dont agree, is not in bad taste. It's taking a dump on every feminist who worked on enabling women to be able to discuss these issues and be taken serious with that.
Cool and interesting idea, but for obvious reasons* I have some slight reluctance with using a service like this for my home. For less valuable targets though -- like a conference room or shared workspace -- this is a really clever solution to sharing keys.

*I hate it when people say that so I'll expand. Simply put, I'm worried about it getting hacked. For instance, could you gain access to someone's wifi and then flash a new image (which includes a rogue key) onto the device?
Social Proof for Unsocial Products
Well you weren't wrong, its the subject of this blog post that App.net has added a monthly model and they've adjusted prices. I agree with you that if the initial wave of folks jump ship it will have failed to reach critical mass.

I expect it will be all about the client capture, which is to say compelling client experiences based on App.net which will drive new development their way.
It is adversarial, because it's a gating mechanism.

Sure, I'll be happy to discuss deep issues with you - after you've shown me that you're proficient in basic CS. It used to be that you could screen that over the phone, but now that you can look up the answers on your phone, that's kind of hard :)

Great UI! One cool idea could be to have automated summarizer snippets already on the page, and let the user edit those, or suggest those to the user. This would result in so much more content.
Yeah. The news is that the earlier projection from the same analyst was 20M. I guess the notion was that Ultrabooks would cannibalize existing netbook and "cheap laptop" sales in a way that they didn't. Instead, manufacturers are chasing the "Macbook Air" market instead, which is at a different price point. And they're not even doing it badly per those numbers. But they aren't hitting what had been expected in the market as a whole.
Value? Enough people are happy to pay $150 for it.

Things should never be priced based on actual expense unless your margins are infinitely slim.
So, do people who use something like this just never lock your bottom handle lock? I live in a busy city and lock both to keep my place secure. I'm not sure I would like just being able to lock the deadbolt but not the handle lock.
PHP's killer app is the LAMP stack and $5 hosting. Unless you can replicate that familiarity on a phone, PHP wont find traction. There are far better programming languages out there with more backing, and I don't think not having PHP has been a major hurdle for mobile development

PHP is the core web language because PHP devs (for the most part) are cheap, replaceable parts. You need to be smarter than that for mobile development, and anyone smart enough for mobile dev won't use PHP if they don't have to.

Yeah, I have hard algorithm questions I ask, but I don't open with them, and I know they are hard. I expect them to possibly fill the entire remaining time.

Also, for the hard question, it's not even about getting it "right": the one person I ever had get my hardest question right was flushed by other people in my process, and I've hired many people who never got close. I want to see how they try.
thanks for the feedback, this is one of the reason (on top of cross-browser compatibility) for which we chose to create a bookmarklet first
Looks great, but I'm reticent to replace my mortise-style door lock. Maybe future versions will support this type of lock? Other than sizing considerations, I don't see why not.
'c interfaces and implementation' would qualify as one imho...
using getCurrentPosition() will have extremely variable results, but watchPositition() will return regular results as it gets more and more accurate.

"more chauvinistic and sexist industries (eg: finance, advertising, previously medicine) appear to be having little trouble attracting women"

I can't speak to advertising, but finance and medicine are some of the few employment traditionally open to women: tellers and nurses. Of course, they aren't traditionally represented in the higher levels of those industries. That seems to be changing, but I suspect the "traditional field" aspect is the key-in-the-door there.

Software, and similar science, technology, and engineering industries, don't have those kinds of traditional positions, making the imbalance more obvious and less, well, fixable.
Anecdotal, but I interviewed for a position where they gave me a tab deliminated data set, and said, "Show us what you can do with this in X language". I had two days.

It was one of my favorite interviews.

First of all, lets be clear: I was responding directly to your statement that one is not required to explain themselves (perhaps you didn't realize I'm not the same person you originally responded to). One's offense does not necessarily require others to change their behavior. To do this requires that you explain how their behavior conflicts with their own stated goals: e.g. to be a good person, or in this case to attract more women to the field.

On the other hand, it is certainly the civil thing to do to avoid causing offense when in public, especially in a professional setting. However, there is still a question of how much one is required to alter their behavior to avoid causing offense. This is why explain the cause of offense is very helpful.

Ask HN: who here has tried LinkedIn ads?
We have B2B Saas product with moderately high CLV. So I'm thinking that LinkedIn ads (at roughly $2 per click) should work great. However, we're not getting very effective click through rates (~ 0.013%), and as a result I think our ads stop getting impressions (looks like LinkedIn throttles ads that aren't very effective).

Who here is having success advertising a B2B SaaS product on LinkedIn?
There was an actual joke in The Office with Michael Scott also confusing "working in finance" with being a teller at a bank.
I certainly wouldn't pay $150 for that, and was asking myself the same ?. It's not going to appreciably increase the value of my home, so an argument that it's home improvement doesn't hold water for me. It doesn't seem to have that much hardware, which would help me understand the price point even if I still wouldn't pay for it.

It simply doesn't solve a problem I have, and at $150, I'm not likely to give it a shot to see if locking my doors manually is really that much of an inconvenience (I doubt it is). I might pay $50, but even then that's a stretch because, as I said, it doesn't solve a problem I've got.
Having taken a lock picking course, I can say that one lock is approximately the same security as two - even after 15 minutes of instruction, with the right tools I could unlock most any standard house lock in moments.

Why not use a lock with a keycode instead? I don't see a single scenario where Lockitron works better.

This is really cool & solves a problem for me. I installed the bookmarklet and am looking forward to using it. I see that you are relying on the community to summarize pages & don't have a large enough data set built up yet.

What would be awesome is if you could somehow automate summarization using NLP. Check out condensr.com. They are able to summarize restaurant reviews...might not be at the same quality level as your current summaries but it came out of research from MIT & could be useful to you.
